p return the contact arms to their normal position, and open the circuit. This arrangement provides an absolute safe-guard against continued closing of thecircuit, so that at each operation of the finger plate, the machine is actuated to mark a check, and the parts are returned to normal positions, regardless of whether the finger plate is released immediately or not. w

- Suitable insulation is provided "on the plunger, and the several contacts, as shown, to prevent short circuiting of the current.

We claim as our invention: 1. In a check protector, the combination with a die, of a platen movable to bring a check into engagement with the die, a pivoted actuating member movable independently of the platen having one end arranged directly under the=platen so as to contact therewith and its opposite end at a point removed from theplaten, an electric circuit, an electromagnet in the circuit having connection with the actuating member at the endremoved from the platen, a switch for closing the circuit and means adapted to be actuated simultaneously with the insertion of a check for operating said switch.

2. In a check protector, the combination with a die, of a platen movable to bring a check into engagement with the die, a pivoted actuatin member movable independently of the p aten having one end arranged directly under the platen so as to contact therewith and its op osite endat a point removed from the pla en, an electric circuit, an electromagnet in the circuit having connection with the actuating member atthe end removed from-the platen, a switch for closing the circuit and means arranged in the path of the check for operating said switch. v

3. In a check protector, the combination with a die, of'a platenmovable to bring a check into engagement with the die, a pivoted member movable independently of the platen having one end arranged directly under the platen soas to contact therewith and its opposite end at a point removed from the platen, an electric circuit, an elec tromagnet in the circuitlhaving connection with the actuating member at the end re moved from the platen, a switch for closing the circuit and means for simultaneously suppglrting the check and operating said SW1 4. In a check protector, the combinationoted actuating member movable independently of the platen having one end arranged directly under the platen so as to contact therewith and its opposite end at a point removed from the platen, an electric circuit, an electromagnet' in the circuit having connection with the actuating member at the end removed from the platen, a switch for closing the circuit, and a finger plate adapted to operate said switch.

6.111 a check protector, the combination with a die, of a platen movable to bring a check into engagement with the die, an actuating member for effecting movement of the platen, an electric circuit, an electromagnet in the circuit for control-ling said actu- I l I u atm member, a switch tor closing the circuit including a pair of spring-controlled contact arms, a plunger having operative engagement withthe cont-act arms, and a finger plateadapt'ed to operate said plunger.

7. In a check protector, the combination with die, of a platen movable to bring a check into engagement with the die, an actuating member for effecting movement of the platen, an electric circuit, an electromagnet in the circuit controlling said actuating member, a switch. for closing the circuit ineluding a pair of spring-controlled contact arms, plunger having operative engagement 1 the contact arms, and afinger plate a pted to operate said plunger, the plunger being adapted for movement independently i the finger plate.

with die, oi a platen movable to bring a check into engagement with the die, an

actuating member for effecting movement' of the platen, an electric circuit, an electromagnet in the circuit for controlling said actuating member, a switch for closing the circuit including a pair of spring-controlled cont-act arms, a plunger having operative engagement with the contact arms, and a linger plate arran ed to engage the plunger in one direction oi movement and to permitfrce movement of the site direction.

H3. In a check protector, the combination plunger in the oppowith a die, of a platen movable to bring a check into engagement with the die, an

' actuating member for efiecting movement of the platen,

' Copies of this patent may be obtained for five cents each, by addressing the an electric circuit, an electromagnet in the circuit for controlling said actuating member, a switch for closing the circuit including a pair of spring-controlled contact arms, a plunger having operative engagement 'with the contact arms, and a finger plate arranged to engage the plunger for closingthe circuit, said plunger being adapted tomove independently of the finger plate for opening the circuit.
